Important moments in food history

You probably ate it on Thanksgiving, but do you know the origins of Green Bean Casserole?

After all, who would think to combine green beans, Campbell's Cream of Mushroom Soup and dried
onions?

Well, as
this article from
International Business Times explains, it was a deliberate attempt by Campbell's to invent
a recipe from things people typically had around the house in the 1950s. (People typically had
dried onions around the house? That seems odd, even for the '50s.)

I don't like Green Bean Casserole myself because it seems like a strenuous effort to hide a
perfectly fine vegetable. But I recognize it as Ohio's State Casserole. As I once wrote, you can
show up anywhere in Ohio with a Green Bean Casserole and know that you will be admitted.
(This despite the fact that the inventor was from New Jersey.)

Next: I'd really like to know who first thought of putting marshmallows in sweet potatoes. That
always seemed like a bad idea to me.
